Accuracy when VOUTx is connected directly to FBx. When the VOUTx voltage is set by external feedback resistors, the absolute accuracy in adjust mode depends on
the tolerances of the resistors used.
Based on an end-point calculation using 1 mA and 200 mA loads.
The dropout voltage specification applies only to output voltages greater than 1.8 V. Dropout voltage is defined as the input-to-output voltage differential when the
input voltage is set to the nominal output voltage.
Start-up time is defined as the time between the rising edge of ENx to VOUTx being at 90% of its nominal value.
Current-limit threshold is defined as the current at which the output voltage drops to 90% of the specified typical value. For example, the current limit for a 3.0 V
output voltage is defined as the current that causes the output voltage to drop to 90% of 3.0 V, that is, 2.7 V.
The minimum input and output capacitance should be greater than 0.70 µF over the full range of operating conditions. The full range of operating conditions in the
application must be considered during device selection to ensure that the minimum capacitance specification is met. X7R and X5R type capacitors are recommended;
Y5V and Z5U capacitors are not recommended for use with LDOs.
